The majority of viruses infected fungi which have been reported contain double-strand RNA (dsRNA) genomes. Mycoviruses are introducing as agent of the biological control of fungi according to hypersensitive properties. In this research, eight isolates belong to Fusariumgenus include ofF. graminearum, F. culmorum, F. tricinctum, F. proliferatum and F. incarnatum survived to dsRNA infection. Due to using of hazardous material such as phenol and complicated procedure in different dsRNA extraction protocols in mentioned research phenol and chlorophorm was removed , using less tissue and dsRNA extraction time was reduced compared to other methods. Result showed that four isolates infected by dsRNA also, mentioned method has sufficient efficiency and convenient for dsRNA extraction from fungi tissue. Also, dsRNA was reported fromF. incarnatum (F. semitectum) for first time.
